This should hold you until that repo is update for Natty (if there ever is one).

The packaging has known to work well, so I won't push the newest revision (which is currently at 1844).

This repo was made specifically made so you can use Natty-built burg and not Maverick-built burg.

=============================================================================
I will be doing a rebuild of both packages for Oneiric. The changes are as follows:
-Append existing entry.
-Adjust the versioning
*To get rid of "+maverick" (for the main package)
*Up the revision to "-2"
-Add line to debian/rules so that it can build successfully with GCC-4.6 (LP: #775460). I've encountered this issue before, and I know how to fix it.

Soon (probably after the release of Oneiric), I am going to create a second Burg PPA. It will be used to try out the newest revision of the package (with Oneiric and maybe Natty). And to see if there were any new bugs added in the newer revisions. I have minimal programming skills, so I can't add anything new to the package.

This will occur somewhere around the official release of Oneiric.
